It can also help to provide a 3D output.I don't know if this will help, but I found a couple things regarding the Cryptographic Subsystem:The only Mac graphic card overclocking utility that supports both Nvidia and ATI cards Take your computer to the forefront of the Mac gaming world. It is tiny and effortless to use. These are designed especially for the ATI cards. It can also monitor the hardware and support nearly 20 languages. ATI Tray Tools is a well-known tweaker application that allow user overclocking the GPU and RAM.
Ati Overclock Tool For Mac This SoftwareHow do I Overclock My HP CPU To overclock your HP processor, find a compatible over-clocking tool to help improve its performance. You only have to learn how to use your overclocking software and follow a guide for the same. Ati Overclock Tools For Mac This software is an overclocking tool for the ATI ATI Tray Tools nTune Is Overclocking Easy Yes.They might be brilliant in some situations, but they don't nessecarily work.For instance on my work pc, a hp dc7800 with an e6750, setfsb can only read the fsb, it can't set it - no matter which of the 3 types I tried (mmt, slp and the other one). That I assume is the reason that gigabyte boards shutdown and restart when changing such settings - to avoid the problem.If you oc from windows, the changes being made are significantly less than from 0 to preset.Regarding the programs - I have some comments on them. Other than being lazy that is.When you're booting your system at an overclocked state, chances are your vrm's can't keep up at powerup for some reason I don't know. This is true both because of effectiveness (some programs don’t display the frequencies well, for example) and because of operating system choice (the majority of the programs we’ve mentioned are only for Windows)."There are advantages to overclocking from windows too actually. To the boot device?Only a theory, but I hope the information helps."We’ll end with a recommendation: it’s sometimes better to overclock via the BIOS setup program.So even though it'd run 20 minutes scanning for artefacts in atitool, a 3dmark test would crash at the nature scene when the lights were rendered. It could set the gpu and mem speed, but the artefact check isn't able to figure out if the shader speed is too high. So on oem systems you may not find the solution you were looking for in software.And atitool didn't work very well with my 8800gtx. Payroll programs for macMust make it hard to sell processors in granularities of a couple hundred MHz when you can overcome that through software without any changes to voltage or mupltipliers.Anyway, good article. To me overclocking was changing the FSB jumper from 1x to 1.5x or, if I dared, 2x.Besides things like cool'n'quiet and whatever Intels version is (Speedstep?), why would chipset manufacturers even open-up software interfaces for overclocking, when for so many years they were completely against it? Now days anyone can click the "+" in Gigabytes Overdrive and gain a few extra percent. On all ati hd48x0 cards I've seen so far, the max gpu setting available in overdrive (790 or so) seemed stable - no need to run the check :)When I purchased my first Motherboard back in 2006 (for the previous 6 years, I had been using a custom-built Alienware, and before that, a Compaq laptop, and before that, a Pentium 166 my dad put together, and before that, and Mac II Se), I didn't understand the point of software overclocking, especially since I had to redo the overclocking every time my machine started up. Perhaps somebody can explain this BSOD:"The Cryptographic Subsystem has failed a mandatory algorithm self-test in bootstrap." (Error code 0x000000123)Forget googling the error code, you'll only find me asking what that means and something else in Chinese.My guess is this-your FSB chipset has different timings/subtimings (like ram does) that are invoked when setting the FSB in the BIOS depending on what frequency is set, and these are referred to as "strappings" (I don't know exactly why, but the reference to "bootstrap" in your error code makes me think this is referring to these "strappings")-some timings/subtimings that work at one frequency (one strapping) are too tight for higher frequencies (in another strapping), so as the FSB is changed in the BIOS, a new strapping is used for the new FSB-it might be that when OC'ing your CPU in the BIOS, you got into a regime in your FSB where the timings just don't mesh well for whatever reason (like there's no good set of timings on the FSB), and some errors are encountered relating to the strapping, spitting out that error code. I have no explanation for it. Windows would BSOD at 3.6GHz or higher on my E6600 even at 1.75V, yet it would be quite stable with much less voltage (although still alot more than most people would dare to try) if I OCed in Windows.
